To all whom'z't may concern: l

Be it known that I, CHARLES A. LIND- sTRM, a -citizenfof the United States, residing at Pittsburgh, Northside, Pennsylvania inthe county fof-.Allegheny and State of Pennsylvania, have invented certain new and useful Improvement-s in Tank-Car Construction, of which the folto-wing is a speci- An object ofv the present invention is to provide an improved tank'car construction of the formw in which, the tank is securely fastenedto the undertr'ame, preferably at `substantially the center of. the carv and supported at or near its ends in such a manner that expansion and contraction of the metal in the tank, due tp temperature changes,

.may take place.

'- f A specilic object of the present invention is to provide atankcar construction-of such acharacter in which the tank is securely fastened yto `the 'underfraine, butin such manner that it may be easily and' quickly removed therefrom. For producing these resultsthewedge -key principle is applied` as aineans-for holding the tank securely to the underframe 1n such a manner as to prever any relative. movement between the Atank and undert'ralne except that due to eX- pansion and contraction of metal.,

curately described in the accompanying specification and shown int-he accompanying drawingsilrii-*hichy like reference charac-k ters refer tolikeparts, and in which;

Serial No. 487,507. y y i Any suitable number of tank stays or i I bands 5' may be employed for assistin Yin holding the tank to the underfranie.4 T esel stays or bands niay also be locatedin'any suitable position relative to ther lengt-h of .p

the car.

y For securely and detachably holding the` tank to its underfrarne and preventin`,`gv rela#y ltive longitudinal movement between lthe tank and its underfranie employ, in the torni of the invention shown in Figs; 1` to 5 inclusive, an anchor castinglor member 6 riveted to the bot-tom of the tank, prefer-V ably ator near its longitudinal center'andl provided' with one or more legs 6a having lateral extensions 6b with perforations 6. These perforated extensions provide widev bearing surfaces. In horizontaljline with the perforatons 6c inthe-depending legs 6 of the anchor castings 6, the center sills 1 'are perforated to receive the combined re inforcing or bearing castings or plates 7 pro@ vided with perforated extensions 7av provid--v ingl wide bearing surfaces and kprojeating throughthe' perforations 1n the center ysills 1. in 'horizontalline with the perforations in` the depending legs 6". AsV shown in Ithe figures referred to each of the legs@a of-the :incluir castings t3 .finden ch .of thecombinedr reinforcing castings or plates 7 are provided f with one or more perforations, (in Figs; 15

110.5 there being two shown) each perfora-A tion belng in horlzontal liney with'its corresponding perforatum in\.theiadjacent partand the several pe-rforations in= the partsbefl v ing` shown in the saine horizontal plane. lIt 1s obvious, however, that any numberfaof perforations may ,be employed 1n eachy of' theseveral parts and that the lines fof perfo- 'A vratiolrisinay lie-.arranged on different hori- .zonta'l planes if desired, without departing i 'troni `the spirit of the` invention. In. comicovtion with..castings t3, and plates 7 Jfor the -purposejof' securely Afastening the tankxto gthe; undrfiramaa wedge or key ,8 is passed throughpeach yline, of pertorations,` just ydescribed, land secured place by a key pin 9 lic dropped through a suitable perforation in the projecting portion of the wedge or key 8. To form a tight connect-ion between the parts and to prevent relative movement between the same, as well as" to enablefthe making of the slots in the sills andprojec;

tions of the same length, thereby reducing\ the cost of production, gib 10 is preferablyV employed which is inserted through a line of perforations before the wedge orikey is driven home. In order to provide for dra ving or driving the several parts together into a tight it wherein relative movement of the parts will be impossible, the several perforations in a line transverse the underframe are arranged in'the same horizontal plane but may be in slightly different vertical planes to allow for what is technically known as draft.t

In the form of construction shown in Figs. G and 7 a single line of perforations is illustrated but the principle of construction is the same as that shown in Figs. l to l5 inclusive. It is also obvious that the dimensions of the several parts may be varie-d in the connection to fulfil differentl requirements as to strength of parts and incidental to different types of tank cars. Furthermore, the securing means described may be located at any position relative to the length and width of the car, but the same is located ,at the longitudinal center of the car for the purpose of allowing for a free expansion and contraction of metal in the tank in both direct-ions from the longitudinal center of the same, the ends of the tank as. already described being so mounted on the saddle that a` relative expansion movement between the tank and saddle may take place; vertically it is preferred to make the location at or near the neutral axis of the sills to equalize the stresses on top andlbottom of sills where the cuttingr away of material is of the least importance. It is also intended that the provision for draft maybe dispensed with, it desired, as shown in the construction illustrated in Figs. 6 and 7, wherein the perforations are in line with each other vcrtically and horizontally, and the wedge or key S may be of any suitable shape.

In the construction shown the tank discharge nozzle 1l is shown to one side of the longitudinal center of the car and riveted to the tank securing or anchoring member 6, although the same may be located in any other suitable position on'the tank. By so locating` the nozzle on the anchoring member ti. it. is possible to extend the anchoring member (l. for strength, to any desired length over the tank bottom without necessitating the loeation of nozzle a great distance trom the renter of the tank. Furthermore,l by rivet ing the. nozzle to the anchoring member instead of directly to thetallk, itis easier to rivet; the same in place, as the riveting will not then be obstructed by the projecting portions of anchoring member 6. Also, if desired, the extensions 7 or 6 may extend in directionsI opposite to those shown on Figs. 4 and 5. For instance, in Figs. 8 and `9 extension 7 is shown extending in a divrection opposite that in Figs. 4 and 5, and

made correspondingly narrower and may further be changed to have a single de ending portion with bosses on the side as s own in these figures. Either construction may be used.

This method of holding a tank to 'an underframe provides a fastening free from loose motion, and, therefore, equally as good as if the tank was riveted by the usual means to the frame, and permits of the easy removal of the tank from the frame for purposes of repairs without the cuttingof rivets, all that is necessary is to remove a wedge or two and the tank can be removed. A further advantage incidental to .this method of fastening a tank to a car underframe is that all shocks are absorbed by parts, such for instance as the wedge or key, which may be replaced easily when worn.

This construction I consider as new and desire to claim broadly regardless of minor changes in details of construction which can readily be made by those familiar with` the art.

Having thus described ny invent-ion, thel following is what I ,claim as new therein, and desire to secure by Letters Patentz' 1.
